Support Markdown in YAML

I would like to have markdown support in yaml configuration.
I want to modify the agency theme:
Here I want to have a word in the text of the header: “Web Security” marked bold. At the moment markdown seems to be not honored in yaml. Is there a way to achieve this without making another sub-sub-page?

It’s not exactly the same, but this plugin does this already:

It looks to targets MetaData but it might work with other headers, or with a very slight modification it might :slight_smile:

I found this in the docs:
and it does exactly what I want.

{{ page.header.text|markdown}}

So maybe the plugin is not necessary at all?

sorry i completely misread your request i was thinking you wanted twig in the header yes markdown is simpler and you can just use the filter
